SPECIFICATION forming part of Letters atent No. 419,652, dated January 21, 1890.

` v Application filed May 29, 1889. Serial No. 312,524.. (o model.)

To all whom it may concern:

Be it known that I, I/VILLIAM F. FOLMER, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Gas-Burners, of which the following is a specification.

I will describe a gas-burner embodyingmy improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure l is j ing upwardly from the socket a to the cavity i a3, and, as here shown, `of the plug A. Above the cavity a3 a side view of a gas-burnerv and appurtenances embodying my improvement. Fig. 2 is a similar view showing the parts in a different position.' Fig. o is a sectional side elevation of the burner and appurtenances as seen in a plane at right angles to that of Figs. l and 2. Fig. tis a horizontal section of the same, taken at the plane of the dotted line a; oc, Fig. Fig. 5 is a view of a burner-body, a ratchet on the plug of the burner, a lever, and a pawl carried by the lever and engaging with the ratchet. Fig. 6 is a side view of' certain parts, illustrating a modification. Fig. 7 is a horizontal section of the parts shown in Fig. 6.

Similar letters of reference designate corresponding parts in all the figures.

I will refer first to the example of my improvement illustrated by Figs. l to 4, inclusive.

A designates the body of the burner. It may be of any desirable form. It is shown as having at the lower end an internally-screwthreaded socket a and at the upper end an internally-screwthreaded socketv a2. The socket a is for fitting a nipple on a gas-hxture. The socket a2 receives a pillar B, which may beof any desired construction. To the pillar B is fitted a globe C, adapted to slide up and down along' the pillar.

The body A is provided with a cavity as,

made of conical form and extendinghorizontally through it and receiving a plug A. This plug is intended to -rotate and is made of conical form. Around the smaller end of the plug a spring A2 is coiled. At one end this spring extends within a cavity a in the side of the body A. The other end acts against a ratchetwheel A3, affixed to the small end of the plug A. The spring therefore tends to p ull the plug farther into its cavity in the body of the burner, and thereby preserve a tight joint, and also to hold the ratchet-wheel from inward movescrew A4, entering a tapped hole in the small end of the plug and having' a large head ex- 1tending over the outer side of the ratchetwheel. v

In the body A is a port or duct a5, extendin line with the axis the body A is provided with a port or duct a, which corresponds to the port or duct a5 and is in line therewith. The plug A has extending transversely through it a port a7, which may be turned into line with the ports Ca. The body of the burner has also a port a8, which corresponds to the port a5 and is behind it in the sense that it is nearer the small end of the plug, and above this port as it has a port a9 in line with the port a8 and behind the port a6. The plug has a port C610, which is behind its port a7 and parallel therewith. When the plug is rotated so that its port al will be in line with the ports a5 a of the body, the port d10 will be in line with the ports as a9 of the body. Gas may then flow through two continuous passages from the gas-fixture to the pillar B of the burner. These double ports which I have j ust describedadord a free flow of gas, even if made comparatively small in diameter. It is more advantageous to have double ports of this character than to have single ports of larger diameter, because a shorter rotary movement of the plug will sufflce for turning the gas full on and entirely off.

D designates a regulating-screw extending into a tapped hole in the body of the burner. This tapped hole extends parallel with the axis ot' the plug and it intersects the ports a5 and a8 of the body. It may be adjusted so as to leave the port-s a5 a8 entirely unobstructed, or to cutoff entirely the port a5 and project into the port as, so as to more or less obstruct the latter. Thus a single screw is utilized for adjusting both ports.

In addition to the regulating-screw D, there may be a regulating-screw D intersecting the port a, through which the main supply of gas passes to the burner.

Thus far I have only explained the means IOO which provide for the main supply of gas7 or, in other words, the supply of gas for illuminating purposes. I also provide means whereby a torch-light or small flame may be burned when the plug closes the ports through which the main supply passes.

d is a port extending from the socket a of the body A upward through the body to its socket a2. This is of such dimensions as to allow but a small supply of gas to pass through it to the pillar B. Ascrewaz, working in a tapped hole in the body of the burner, may be adjusted to more or less obstruct the port du to regulate the supply of gas afforded by it. It will be seen that the cavity ctiwhich accommodates the plug, is arranged so that its center will be off to one side of the center of the body. This arrangement affords space for the port a directly through the body within the line of the sockets a a2.

Er` designates a lever, which may advantageously be made of sheet metal, having a circular opening e, of a size to iit upon the tips of the teeth of the ratchet wheel A3. This lever may swing or oscillate by turning around the ratchet-wheel. A washer c surrounds the small end of the plug A behind the ratchet-wheel and thelever E. The spring A2 impinges against this washer. The head of thescrew. A4 is large enough to bear against theouter side of the lever E. The ratchetwheel and lever are therefore held between the washer e on the one side and the head of the screw Af* on the other side. The head of this screw conceals the circular hole e in the lever. The lever has a spur e2, which is adapted to coact with a pin e3, projecting froijn the burner-body, to limit the swing of the lever in one direction. The lever is moved in this direction by a spring S,here shown as of volute form, connected at' one end to the pin e3 and at the other end to a pin e4, affixed to the lever E. The lever is swung in the reverse direction by manual force. This may be conveniently applied through a cord" or chain eattached to the outer end of the lever and hanging therefrom.

From the opening e of the lever an arcshaped opening or notch e6 extends. In this opening is a pawl e7, which is pivotally connecte'd Awith a lug es, forming part of thelever and engaging with the teeth of the ratchet wheel. Preferably the lever will be thicker than the pawl. NVhen this is the case, the lug may be bent forwardly or outwardly to a very slight degree, to enable the pawl to be accommodated within the opening or notch c6. The pawl will preferably be provided with a transversely-exten ding lug, which will extend under one of the coils of the spring S, so that it will be caused to quickly engage with the ratchet. When the lever is oscillated in one direction by the spring, the pawl will play over the teeth of the ratchet-wheel. Vhen the lever is oscillated by the chain e5, the pawl will engage with one of the teeth of the vratchet-wheel and effect a partial rotation of the yplug A of the burner. It will be .observed that the ratchet-wheel has but four teeth. The downward movement of the lever, caused by a pull upon the chain e5, is limited by a projection or spur c, formed upon the lever and coactin g with the pin e3. The lever, it will be seen, is capable of moving only about a quarter of a circle. It is intended that each pull of the chain e5 shall effect a quarter-rotation of the plug. Owing to this the ports a7 am of the plug will be by one pull of the chain moved into a vertical position and by the next pull of the chain moved into a horizontal position, so as to cutoff the main supply of gas, and so on.

In Fig. 6 I have shown that the leverE may be hung upon the small end of the plug of the burner in rear of the ratchet-fwheel and provided with a weighted pawl pivoted to it by a pin Z as a substitute for the pawl which I have heretofore described actuated by the spring.-

The globe C may be made o f glass, mica, metal, or other suitable material. It is intended to protect thetorch-lightor small flame from currents of air. It is shown as supported in a globe-holder C', which may be made of a 1, perforated disk of sheet metal fastened to a adapted to be slid along the same. The globecorrugated sleeve c, fitting the pillar B, and

holder may have flanges or claws for einbrac-Y ing the lower edge of the globe. The globeV i is intended to be slid up, so as to encircle the tip of the burner while the torch-light or small flame is to be burned, and to be lowered below the tip while an illuminat-ing-flameis de-V a sired. It is raised and lowered by means of g a lever G and link I.

The leverA is oscillated through the plug of the burner, and the link is connected at one end to the globe-holder and at the other to the lever. It will be seen that the link is bifurcated, so as to connect -with diametrically-opposit-e points ot' the globe hold er.

One of the bifurcated arms 1s straight or substantially straight, so as to reach the lever G, the latter being at the back body of the burner.

of the body of theburner.

The lever G is fulcrunied by a pin g to the It has an opening g',

' which is mainly of ellipsoidal form, although at o-ne point it has a shoulder g2 and at another point a projection or salient surface g3. On the large end of the plug'A A are twolpins or projections g4 g5. These extend through the opening g and act one at a time upon the shoulder g2 and the salient surface g3. When either pin or projection g4 g5 cont-acts with the shoulder g2, it will raise the lever G to its highest position. This will occur at every alternate downward swing of the lever E, and at such time as the downward swing of the lever E rotates the plug to move its ports out of line with `the main supply-ports in the body ofwthe burner. On each downward swing of the lever E, which brings the ports of the plug into line with the supply.- ports in the body of the burner, one of said TOO IIO

pins will contact with the salient surface g3 of the lever G and lower the lever. These movements of the lever G will eifect the raising' and the lowering of the globe C. I prefer t0 provide enough play or lost motion between the engaging of the said pins with the shoulder g2 to allow the main gas-supply ports to be opened fully or entirely closed before a pin shall become disengaged from the said shoulder and contact with the salient surface g3.
